Some insulation around or under the threads would be advised. We found that those screws were very close to the aluminum and with any deflection they could rub the bars.

But the real issue we experienced with the railblaza Aka mounts, is that balanced 2-sided fitment was needed to seat them properly in place. Very easy to torque one side more that the other.

On the rounder AI Akas and crossbars bars, the proper number and placement of the spacers determined how well they held (think loading them with large reels and big fish strikes). A 1/2 spacer gap (too big or small) made them ineffective. Plus they came with sandpaper grip inserts that did not fit all diameter bars well.

CC's are paired together which helps with overall grip. But as a solo mount, they need to be tuned just right to support decent loads. We found that the right number of spacers helped stabilize it.
